Pick the Right BMS
Uses a JBD Bluetooth BMS. Motor watts help you find a tier, but your controller's battery current decides it.
Battery current decides the tier.
| Tier | Peak | Max power | Controller |
|---|---|---|---|
| 30A | 90A | 1500W | ≤25A |
| 40A | 120A | 2000W | ≤35A |
| 60A | 180A | 3000W | ≤50A |
Same 1440Wh all tiers. Range depends on riding style, not the tier. Estimates only. Controller limits are suggested values.

FAQ
Will this fit my 72V eBike?
Yes, if your system is 72V and your controller handles 84V full charge. Check your frame triangle first: Length 280 x Width 175 x Thickness 75 x Diagonal 220 mm. Leave room for cables and terminals.
Which BMS tier should I pick?
Pick by your controller's battery current, not just watts. 30A for up to 1500W, controller ≤25A (suggested). 40A for up to 2000W, controller ≤35A (suggested). 60A for up to 3000W, controller ≤50A (suggested). Peak is 90A / 120A / 180A.
How long does it take to charge?
About 4-5 hours with the included 84V 5A Fast Charger. Mains first, then battery. Disconnect battery first, then mains.
How far will it go?
It depends on how you ride, not the BMS tier. All tiers share the same 1440Wh. Pedal assist on flat ground goes furthest, full throttle uphill cuts range sharply. Estimates only, no fixed miles number.
Which connector should I pick?
Match your motor plug and cover your BMS current. QS8 is about 180A, XT90 is about 90A, XT60 is 60A, Anderson SB50 is 50A. For the 60A tier, pick XT90 or QS8. Wire only is also available. Send a photo of your motor plug if unsure.
Is it waterproof?
No. It has a PVC wrap and top seal, spray and rain safe. Do not submerge it and do not ride through deep water.
What does the 2-year warranty cover?
It covers the battery pack for 2 years, not the charger. If you need a claim, send your order number and a full BMS report to support@booant.com. Do not return the pack without approval.
